What I was thinking:

- Pick a corner point
- Width automatically gets a predefined value
- Pick the orientation of the first side
- Height automatically gets a predefined value
- Pick the orientation of the second side
- Extrude.

The reason i want this is for a timber framing project and I want to create lots of beams with the same dimisjons. I am not sure this is the best way to do it but it is how I have been doing it manually.
